v17 Pro SP1 Hotfix 2 - Win8.1 - Google Integration

Have any of you come across any issues with Google Integration when using ACT! v17 Pro SP1 Hotfix 2?

It works initially, but the schedule doesn't appear to get followed, and as such, its a once off job, requiring manual invokation.

My concern is that upon launching the Google Integration applet, it complains about requiring .NET framework 4.0, which supposedly is already supplied within Win 8.1, and as such, isn't possible to install as an addition.
